On the evening of November 29th, a deepening surface low over the upper Mississippi Valley dragged a warm front northward from the Gulf of Mexico. Surface dew points shot upward into the 60 to 68 degree range across much of central Alabama. Additionally, a strong cold front was approaching the area from the west providing even more lift. Surface-based instability simultaneously shot upward with Storm Relative Helicity values of 300-500 m2/s2. This combination of parameters created multiple nocturnal supercell thunderstorms. These supercells exhibited strong rotational velocities at times, but only managed to create 6 relatively weak tornadoes across the area. The strong storm system did however produce tornadoes in Louisiana, Mississippi, Alabama, Georgia and South Carolina. Here is a summary of those events:
